Overview:

The APR Catback Exhaust System personalizes your vehicle's looks, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. Cast 2.75" to dual 2.5" rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system. Our cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation.  Finally, removable 4" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle. Optional tip upgrades, and an optional center muffler / Center muffler delete is available.

8.5 sound out of the box! (Want bespoke configs? Sorry.) Great Value, Easy Setup
Style: AVR-X1800H
Excellent unit. Off the shelf sound is very nice, but every room is different, so a bit of tweaking is usually required. Accessing the EQ settings takes a bit of sleuthing and the use of its app... which is subpar. The app interface can only be explained as designed by people who must not actually use it. Still, a wonderful machine at a fair price. I run in ECO mode and it powers my 35x47 room with plenty of power to spare and NEVER gets hot. I am running Infinity Reference speakers and a Klipsch sub in a 7.1 config. I highly recommend the use of the included Audyssey calibration microphone! My prior experience with Yamaha YPAO left me wondering what was the point. This time with the Denon, it set up the speakers, (i'm embarrassed to say) better than I did on my own. (To be fair, I'm sure Yamaha has improved its YPAO in the decade since my prior purchase) Bottom line. If you want maximum flexibility on EQ. Shop a different solution. However, If you want quality sound with 4K and up to and including ATMOS processing, with minimal tweaking, or just want to unbox and play, this is a wonderful unit at a very fair price.

Does well for my needs
Style: AVR-X1800H
I got this to replace a Sony head unit that was starting to fail after 10 or so years of use. This one doesn’t have the same power output, but I use Bose speakers. Bose is fairly low wattage for the most part so no problem there. Setup was fine. My only complaint is that center channel only dialog is too quiet. I need to adjust that. Everything else is great. I don’t care about Internet connectivity, but it has that if you want it. I’m very happy so far with this unit.

Nice AVR
Style: AVR-X1800H
Refurbished and looking like brand new. One small scratch on the side. It went in a cabinet and it's hidden. All paperwork seemed to be there. If I didn't know it looks like factory sealed . I've got an older Denon. Just wanted to move up to 7.2. Audyssey recognize a second sub. But neither did my older on. No problem with that though. Just FYI. After the original setup and minor tweaking it sounds fantastic for me. I haven't had it but a few days and I hope I get many years of enjoyment from this
